31、, A and B, to demonstrate the coincidental acceptability ofhexagon height, corner fill and width across corners. Gauge A shall be placed over the nut and shall be seated on theflange. Gauge B shall be placed on the top of the nut normal to the nut axis. The two gauges shall not be in contact.A.2 Rec
32、ommended method for gauging of flange thickness (see figure A.1 and table A.1)Gauge C is a flat feeler or ring gauge. It is used to prove that the flange thickness at the junction with the hexagonportion is equal to or greater than specified values. The acceptance criterion is that gauge C shall fit
